HUB AND rnLLYsTnU'crUnE i 01. R'EsILiENEr wnEELs.

a citizen of the United States, residing at Oakland, county of Alameda, and State of California, have invented new and useful Improvements in Hub and Felly 'Struc-' tures for Resilient Wheels, of which the'following is a specification.

This invention relates to resilientv wheels and especially to a hubv and felly structure therefor.

The object of the present invention is to generally improve and simplify the hub and felly structure of resilient wheels, andespecially that type employing spring spokes,

. and further, to embody in the hub and felly a structure which provides ample bearing areas for the opposite ends of the spring spokes and which also permits ready insertion and removal of the spokes .tor'inspection, repairs, or otherwise.

One form which my invention may assume is exemplified inv the following description and illustrated in the accompany ing drawings, in-which- Fig. 1 is a side elevation of a resilient wheel employing spring spokes, said view showing the hub and'felly structure partly in side'elevation and partly in section.

- Fig. 2 is a cross sec'tion on line 2 2, Fig. f V Fig. 3 is a side elevation'of thefelly. Fig. 4 is a cross-section of the same.

Fig. 5 is a side elevation in section taken on line 55, Fig. 6.

Fig. 6 is a cross-section of the hub struc ture.

Fig. 7' is a plan view of one of the hub spacing members.

Referring to the drawings in detail, and particularlyto Figs. 1 and 2, A indicates the hub ofa front wheel such as used 'on Ford automobiles, B the'hub forming the subject-matter of the present application, 0

tween'the hub B and the felly G, and?) a demountable rim, hereinafter to be referred to; The. hub proper is perhaps best illus-' trated in Figs. 5 and 6. Thehub is constructed of two separable sections a's indicated at 4. and 5. These sections are preferably constructed of pressed steel and each section is provided with a hub portion 6, which'forms a. spacing member between the the telly, 2 the spring spokes interposed bespaced relation by means of spacing members such as indicated at 7, the number of spacing members employed being equivalent to one-half the number of spokes employed. The spacing members are perhaps best illustrated in Figs. 6 and 7. They are formed from flat pieces of pressed steel and are curved in cross-section. toform a supi. port for the lower spring spoke eye, as will hereinafter be described. The ends are re duced, as indicated at 8, and the center portion of each s'pacer is grooved, as indicated at 9, to form a receptacle forgrease or any other suitable lubricant. The hub members are perforated to receive the reduced ends 8 of the spacing members 7 and these reduced ends are either clinched, welded, or other- -wise secured. The'hub B, in other words,

consists of two sections of pressed steel which form the hub 6 and side flanges a and 5, said side flanges being spaced apart by the hubsection 6 and the spacing members 7. The separable sections of the hub are permanently secured and tied with relation to each other when the reduced ends ofthe spacing members 7 are clinched or otherwise secured. l

The hub B is received by'the standard hub A, being pressed over the same or otherwise fitted. The hub A is provided with a flangebeing pivotally connected with a common pin as indicated at'10. This pin is secured "between the flanges 4 and 5 of the hub B,

asillustrated in Fig.2, and the spring eyes are allowed acertain amount of turning 'movem'ent about the pin. Again, it is obvious that the spring eyes may be rigidly securedtothe pin and that the pin may turn between the flanges 4 and 5 if desired.

- As previously 'stated, the spring spokesare' arranged in pairs'and thelower ends are connected to a common pin'lO. One spring spoke of e'ach pair, as indicated at ammunat'es in an eyell'which surrounds the pin v 10, while the 'second's'poke of a pair, indi dicated at 2, terminates in an eye- 12 which surrounds the eye of the spring spoke '2. The position of thespacing members 7 is such'that they'enga e the'outer surface of same; They are-furthermore maintainedin theeyes12andjas sue form a-bearing memion ber or partial support therefor, and, to this extent, relieving the load on the pins 10. The outer ends of the spring spokes also terminate in eyes, as indicated at 1 3, and 5-. these eyes surround pins 1a secured'm the-- ielly C. The telly is annularin'construction and channelled-shaped,as shown in Figs. 3

and 4, and is constructed'of rolled steel. The bottom portion or, inner surface of the. i telly is stamped or perforated at spaced intervals, as indicated at 15, to permitinsertion of the spring spokes: and to permit a certain amount of play.. The bottomportion of the telly is also pressed or rounded I in alignment With each -pin 1,4,as at 16,; to

form a s'eat for the respectivespriiig eyes 13, thus increasing tlie bearing area and, to this extent, relievingthe pins 14 of a proportional amountlof .load strain, Wear, etc.

The sides of the telly indicated at 17 and 18 are perforated to receive the pins M, which may turn therein orthey'may be permanently secured as desired; that is, the eyes 13 of the springspohes maybe pen manently fastenedto the pins and the pins permitted to turn in the side fianges oit the hub, or the pins may be riveted or otherwise secured between the side jflanges and, the eyes permitted to swivel about the pins. A

permanent spacing .maintained between the side flanges 17' and 180i the telly by transverse webs 19.. These Webs are arranged at regular intervals, as shown in Fig. 3, and they are formed by punching the bottom portion of the f elly and turning the punched portion upwardly and outwardly as illustrated. The members 19 therefore maintain a permanent spacing between the side flanges and the hub, and

iiirtherinore reinforce and strengthen the same. I 1 v Any suitable type, of 1 demountable rim may be employed, but a four-lug, rim is in thisinstance illustrated; that is, the rim is any suitable type of rim.

By referring l and EZ, it Willbe noted that enclosing disks, such, as illustrated at 2 5 and gti are jemployedr :Thse dis ser th unptien o enclosing :f

The specific"structure of the enclosing disks, the niethod of applying and securing the same, etc., Will not be described in detail in the present application as it forms the subject-matter of a separate co-pendmg application filed by me on March 19, 1923,

Serial No. 626,060, entitled Disk wheel.

From thefi'oregoing description submitted, 1t can be seen that. an exceedingly simple and rigid hub and telly structure has been provided, Which'maybe attached to practically any standard form .ofwl1eel hub; thatthe spring spokes employed may be readily inserted or removed toiyinspeotion, repairs,

etc. that means areemployed for relieving the bearing pins of excess strain, as added bearing area has been provided by the spacingmembers'? and thebent portions ot'the telly indicatedat ltipthe members 16 and 7 being grooved to receive and retain'an additional 7 quantity oi. lubricant. further be seen that an ideal resilient action may beo'btained between the telly and the hub due :to the method oi securing or at-' taching the spring spokesas these are perm tted to freely sivivel when the Wheel IS in operation. It. can furthermore be seen that the spacing members 7 and the bent portions 16 alsoformstops Which limit er cess swivelling movement. .Again,,byr'eferring to 'Fig. 2, it Will'be noted that the width of the spring spokes 2 is such that practically no side play is provided, this being of great importance as .it'materially increases the lateral strength of the, Wheel, and furthermore avoids rattling and Wear.

Awvheel constructed as here illustrated usually employs a solid rubber tire, but in some instancespneumatic tires are used. In

It can 'i (ll) that instance, it would only be necessaryto perforate the bottom portion of the telly to permit the valve stem to pass therethrough,

this beingaccomplishe'd,Without changing r the structure in any manner as the perforation can'be formed at any point desired between the spring spokes.

While certain features of thefpreseiit invention are more or less'specificallyTillustrated, I Wish it understood that various changes in form and proportion'may-be resorted to Within the-scope of the appended claims; similarly, that the materials and finish. of the several parts employed may be such as the experience and judgment of the manufacturer, may dictate or various uses may demand.
